Input: atmel_mxt_ts - add maxtouch to I2C table for module autoload

Browse Source 
The Atmel maxtouch DT binding documents that the compatible string for
the device is "atmel,maxtouch" and the I2C core always reports a module
alias of the form i2c:alias where alias is the compatible string model:

$ grep MODALIAS /sys/devices/platform/12e00000.i2c/i2c-8/8-004b/uevent
MODALIAS=i2c:maxtouch

But there isn't maxtouch entry in the I2C device ID table so when the
i2c:maxtouch MODALIAS uevent is reported, kmod is not able to match the
alias with a module to load:

$ modinfo atmel_mxt_ts | grep alias
alias:          of:N*T*Catmel,maxtouch
alias:          i2c:mXT224
alias:          i2c:atmel_mxt_tp
alias:          i2c:atmel_mxt_ts
alias:          i2c:qt602240_ts

So add the maxtouch entry to the I2C device ID table to allow the module
to be autoloaded when the device is registered via OF.
